Bony Thorax Flashcards
What is the best position to utilize in order to adequately remove the sternum from the vertebral column?
RAO
The proper breathing for a lateral sternum should be –1–.
Deep Inspiration
The proper respiration for AP upper ribs should be –1–.
Deep Inspiration
There are –1– pairs of false ribs.
5 pairs
The scalloped edged appearances on the body of the sternum are called –1–.
Costal Notches
The sternal angle is at the approximate vertebral level –1–.
T4
The xiphoid process is at the approximate vertebral level of –1–
T10
Another name for the body of the sternum is the –1–.
Gladiolus
According the Merrill’s, the best position to use in order to demonstrate axillary ribs is the –1–.
Oblique
Ribs that have a direct anterior attachment to the sternum are considered to be –1–.
True
The –1– of the vertebrae and the –1– of the rib, form the costotransverse joint.
- Transverse process
2. Tubercle
When performing oblique rib positions on a supine patient, the elevated or side up ribs will appear –1–.
Foreshortened
When performing oblique rib positions on a supine patient, the side down ribs will appear –1–.
Elongated
The RAO position of the sternum is preferred because –1–
It puts the sternum in the homogenous densities of the heart.
List the two breathing methods that may be used when performing the RAO of the sternum.
- Short, shallow breathing with long exposure
2. Expiration
According to Merrill’s, in order to best demonstrate the anterior ribs the patient should be placed in the –1– position.
Prone
What is the preferred scale of contrast used for rib exams and explain why?
Short scale/high contrast because trying to visualize bones. Don’t want a lot of shades of gray because it will take away from bony detail.
Proper respiration for AP lower ribs should be –1–. Why?
- Exhalation
2. It will elevate the diaphragm allowing for a better visualization of the lower ribs.
When performing oblique rib positions, the patient should be rotated –1– degrees.
45 degrees
What is meant by partial or incomplete or unilateral ribs?
Only focused on x-raying one side of the patient. If the order says L Unilateral Ribs, you x-ray the L ribs of the patient and vice versa if it said R.
What can be placed at the injury site for ribs in order to assist the radiologist when interpreting the image?
Lead BB
How many degrees should the patient be rotated when performing an oblique sternum position?
15-20 degrees
When performing an oblique sternum, the CR should be perpendicular and directed to mid-sternum or approx. T7. Explain how you would achieve this by using bony landmarks as a guide.
C7 is the vertebral level of the vertebral prominence, so I would put the top of my film at this prominence by feeling the spine and then off set 1 inch to the left of the patient’s spine.
What is the recommended SID for an oblique sternum that will help blur out the posterior ribs, –1–?
30 inches
Explain what positioning maneuver must be done in order to adequately demonstrate the sternum in the lateral position.
The patient must clasp their hands behind their back if possible, roll their shoulders back and jutt their chest out forward. Then tell them to take a deep breath in to further push the sternum in profile.
According to Merrill’s, when performing oblique ribs to demonstrate the axillary ribs on the prone patient, the affected side will be –1–.
Away/elongated
The SC joints require –1– degrees of rotation in order to move them from the spine.
10-15 degrees
Proper respirations for SC joints should be –1– to achieve more uniform density.
Expiration
SC stands for –1–.
Sternoclavicular joint
Why are SC joints performed utilizing the PA projection?
To decrease magnification
The CR should be perpendicular and directed to the –1– for PA SC Joints.
Manubrial Notch
When would it be appropriate to perform ribs in the upright position?
When the patient can’t lay supine on the table.
According to Merrill’s, when is it appropriate to perform ribs in the recumbent position?
When the patient can lay supine/prone and able to roll 45 degrees in both directions.
Proper respiration for lower ribs (ribs below the diaphragm) should be –1–.
Exhalation
If a patient could not lie prone for the routine oblique sternum the equivalent position would be –1–.
LPO
If using filtration on bilateral oblique ribs, where would the thick portion of the filter be placed, side up or side down?
Side up
Name the function of the SC Joints.
Attaches upper limbs to the trunk
Ribs that have NO ANTERIOR ATTACHMENT AT ALL are called –1–.
Floating
What two structures make a costovertebral joint?
Head and vertebral body
The CR is directed –1– for the oblique image of the sternum.
1-2 inches to the left of the spine
The axial os calcis requires a CR angulation of –1– degrees –2–.
- 40 degrees
2. to the long axis of the foot
List the three things (equipment operations) that must be done for any exam when there is a film in the bucky.
- Tube in center
- Bucky tray slot cover closed/pushed in all the way
- Tube and bucky lined up
